Threat Hunting with Elastic Stack

5 (1)
By: Andrew Pease

Overview of this book

Threat Hunting with Elastic Stack will show you how to make the best use of Elastic Security to provide optimal protection against cyber threats. With this book, security practitioners working with Kibana will be able to put their knowledge to work and detect malicious adversary activity within their contested network. You'll take a hands-on approach to learning the implementation and methodologies that will have you up and running in no time. Starting with the foundational parts of the Elastic Stack, you'll explore analytical models and how they support security response and finally leverage Elastic technology to perform defensive cyber operations. You’ll then cover threat intelligence analytical models, threat hunting concepts and methodologies, and how to leverage them in cyber operations. After you’ve mastered the basics, you’ll apply the knowledge you've gained to build and configure your own Elastic Stack, upload data, and explore that data directly as well as by using the built-in tools in the Kibana app to hunt for nefarious activities. By the end of this book, you'll be able to build an Elastic Stack for self-training or to monitor your own network and/or assets and use Kibana to monitor and hunt for adversaries within your network.

Installing and configuring Kibana

Now that we've deployed Elasticsearch, we need to build Kibana. A deployment of Kibana is pretty simple, and connecting it to Elasticsearch using basic authentication isn't terribly difficult either.

Installing Kibana

As we've already installed the Elastic repository, we can simply use that to install Kibana using yum or DNF and enable it to start on boot:

$ sudo dnf install kibana

$ sudo systemctl enable kibana

Now that we've installed and configured Kibana to start on boot, we can continue to connect Kibana to Elasticsearch.

Connecting Kibana to Elasticsearch

Kibana (and Beats for that matter) uses a Java KeyStore to manage and secure credentials. We're going to add elasticsearch.username and elasticsearch.password to the KeyStore.

This is the username and password used by Kibana to authenticate to Elasticsearch. We set these when we configured all of the credentials during the Elasticsearch setup. elasticsearch...
